      Changing minimal JDK requirement has huge impact for most users as both jenkins master and slave need to be upgraded. As JDK 7 will be EOL soon, it seems a better choice to me to directly move to Java 8

      • users to discover this compatibility break will only have to upgrade one
      • impact on jenkins development is far more exciting.
